A study of children's musical preference: a data mining approach

This article studies the musical activity preferences of 228 young children (aged 4–5 years) from Hong Kong, China, and Adelaide City, Australia.

Features, objects, and other things: ontological distinctions in the geographic domain

Response of 263 subjects giving examples for one of five geographic categories (geographic features, geographic objects, geographic concepts, something geographic, and something that could be portrayed on a map) are analyzed. The frequencies of various responses are significantly different, indicating that the basic ontological terms feature, object, etc., are not interchangeable but carry different meanings when combined with adjectives indicating geographic or mappable aspects. Viscovery SOMine is used for training and initial labeling of neurons, and ArcView is used for processing base map configurations and two-dimensional interpolation.
